4 | Subject: [PATCH 09/11] Fix possible NULL dereference | ||
5 | |||
6 | Fixes a possible NULL dereference if memory for | ||
7 | the PosixNetworkInterface could not be allocated. | ||
8 | Other logic seems to prevent dereferencing this | ||
9 | variable if NULL, but this instance seems to have | ||
10 | been overlooked. | ||
